Aspects:
Weldability:
The surface of the cold rolled sheet must be clean, with white, unpolished
aspect, being admitted some local marks of oxides:
• pores and scratches
• unimportant tracks as a result of the falling of the oxides and tracks of rolling
• slight yellow dyeing from the pickling
On the cut edges of the strips, there are not admitted exfoliations and ruptures
visible to the naked eye.
The cold-rolled strips can be welded. Weldability is warranted by the chemical
composition.

Domains of use:
Aspects:
They are used in the machine construction, support structures for
machines and equipments, metallic constructions, in the case of
some mechanical moderate demands.
The surface of the strips must be clean and smooth, without any
covers, cuttings, air holes, scratches, non-metallic and scale
inclusions, lacks of material, superpositons and stratifications.
There are admitted the following defects of surface:
• small local scratches and air holes, local exfoliations, inequalities
resulted from rolling, in the limits of the deviations accepted in the
case of the thickness
• a thin layer of oxides
• unevenness resulted from rolling or that remain after the falling of
the scale, in the limits of the negative deviations to thickness
But, there is not admitted the correction by welding of the surface
defects. There are not admitted, on the cut edges, any exfoliations
and ruptures visible to the naked eye. The strips must have their
edges cut in right angles.
Delivery terms:The strips are delivered in annealed states, planed (cold hardened), covered
with a fine coating of oil of protection easily washable. The strips, after a
corresponding preparation, can be painted, galvanized, etc.
Domains of use:• for metallic and mechanic constructions, car industry,
agricultural machines, household commodities
• for products that are going to be worked off by cold
deformation and especially for cupping
Weldability:
Delivery terms:
The attitude at welding and after welding depends not only on the
material, but on the constructive conception too, on the
conditions of execution and on the exploitation of the
construction elements. The attitude at welding can be verified by
the homologation of the welding process, respectively of the
welding technique.
The sheet are delivered in rolled state or in normalized state
obtained by the control of the temperature during and after
rolling. The sheet with cut edge with the thickness to 40 mm are
going to have their edges cut only by mechanical means, and
those with the thickness over 40 mm are going to have their
edges cut only by flame.

Domains of use:
The steel sections are not treated after the cold-rolling. On the external and internal surface, there can appear
tracks of emulsion, respectively smaller tracks of oxidation. On the external surfaces of the sections there is applied
an oil covering, that assures a provisional protection against corrosion. At request one can renounce to this
protection covering.
The minimal and maximal figures of length are:
Standard
Tolerance on length
On a separate order, there can be realized special dimensions.
Tolerance to length is much lower than, those previewed in standards.
The mass of a section is of maximum 100 kg..
The cold-rolled sections have a large area of use, as a result of the large offer from the point of view of the forms,
dimensions and the materials'quality.
• optimal ratio between the mass on unit of measure and the parameters of the section
• it can be easily mounted
• agreeable form and aspect, with smooth surfaces
• level of high precision of the dimensions (low tolerance)

can be easily assembled, so their costs of processing are low, large palette of dimensions, low tolerance,
smooth surface that allows to the constructor the realisation of a clear and functional design.
Corresponding weldability for optimal processing
The raw material of high quality meets the clients'demands of quality in the field of the steel's purity, malleability and viscosity.
These sections distinguish especially by their very good weldability at the edges, too, with the following characteristics:
•high resistance to rupture and to low temperatures
•raw material of totally deoxidized steels
•equivalent carbon maximum 0,43%
•the realisation of the edges according to EN 10219
•the lack of the fissures at the edges, as a result of the raw material with an excellent malleability even in the case of the
categories with a high resistance

Mechanical caracteristics
Domains of use:
Pipes of carbon steel, longitudinally welded, un-galvanized
(black) or galvanized, threaded or unthreaded (smooth) are
destined to the realization of the network of transport of the
warm and cold drinking water, of the plant heating and of the
transport of thermal agent with maximal pressure of 50 bar,
respectively the realization of the technological installations.
The superior quality of the utilized material makes possible the
appreciation of the life duration of minimum 15 years of the
products with the respect of the appropriate anticorrosion
protection rules.
Lengths of delivery:
• lengths of manufacturing: 4,6,8 m
• exact lengths within the manufacturing lengths
• multiples of the exact lengths
Pipes with multiple lengths of the exact lengths, included within
the manufacturing lengths are delivered with an addition of 5
mm for every cross-cut, if not provided otherwise in the orders.
Deviations:
The limit deviation for the lengths is of: +0-100 mm.
The limit deviations for the thickness of the wall are of: +/-
12,5%, and in isolated places respectively for lengths which do
not surpass twice the external diameter a deviation of -15%.
Limit deviations of the mass for every pipe: +/-10%
Aspects:
The external and interior surface of the pipes must be smooth,
without fissures, cracks, superpositions of the material, non-
metallic inclusions. There are admitted small scratches,
eminences, hollows, a thin mill cinder or traces of cleaning of the
faults resulting from the manufacturing process, so that the
thickness of the wall should not fall under the admitted minimum
limit. The welding joint must be compact and continuous,
without fissures or other faults, which would reduce the
resistance of the welding joint under that of the basic metal.
The external prominence of the welding joint is moved off. The
thickening of the welding joint is admitted within the limits of limit
deviations for the external diameter. The interior burr of the
welding joint is not moved away. Unevenness of the margins of
the strips in the welding joint is not admitted. The ends of the
pipes must be smoothed perpendicularly to the axis of the pipe.
At the endings of the pipes, there is admitted a burr, resulting
from the technological procedure of cutting. There are not
admitted the strains of the endings of the pipe.
The galvanized pipes must have on the external and interior
surface an adherent and continuous zinc coating. The covering
with zinc on both surfaces or only on the interior surface is
carried out by immersion in melt zinc bath. Local roughness and
thickenings of the zinc coating are admitted, more pronounced
on a portion of 80 mm from the ending of the pipe, where the
blowing of the pipe is executed.
The thickness of the zinc coating on the external surface must be
smaller than of the interior surface.
The thickness of the zinc coating on the interior surface must be
of approximately 56µm. The linear mass of the galvanized pipes
is calculated by addition, to the mass of the pipes of the quantity
of the zinc corresponding with the minimum thickness of the
layered zinc coating.
Longitudinally welded steel pipes
Protection:
With the agreement of the parties the pipes may be delivered
protected against corrosion through oiling or other adequate
procedures.

the dimensions marked with the * sign are delivered only on
the basis of a firm order
Aspects:
The external and internal surface of the pipes must be
smooth, in accordance with the manufacturing procedure.
inside and outside surfaces must not have any fissures,
superpositions of the material, blowing, metallic inclusions or
other faults visible to the naked eye. Small eminences,
breaches and traces resulting from the cleaning of the faults
of the surface are admitted with the condition, that their depth
should not surpass the negative deviation at the thickness of
the wall. With pipes with an internal diameter under 15 mm
smooth interior surfaces are not warranted.
Protection:
• unprotected
• covered in exterior with black or uncoloured lacquer
• oiled in exterior or in the exterior interior part
• at request, the endings will be provided with plastic
protection
Delivery terms:
The pipes are delivered with cold hardening or heat
treatment. Those with heat treatment (normalized) are
delivered with oxides formed in the technological process of
manufacturing. At request they can be delivered also in other
terms of the surface aspect (normalized in neutral
atmosphere N.A.N. pickled, etc.)
Domains of use:
In construction of implements with technical conditions of
fixed quality as well as in the case of implements of general
use.
Lengths of delivery:
hot-rolled pipes
• lengths of manufacturing: 4-12,5 m
• exact lengths within the manufacturing lengths
• multiples of the exact lengths
• tolerance: +/-25 mm.
• lengths of manufacturing: 4-12,5
• exact lengths within the manufacturing lengths
• multiples of the exact lengths
• tolerance: +/-25 mm.

Domains of use:
Used for metallic constructions, equipments and pipe-lines of general use.
Lengths of delivery:
•lengths of manufacturing:4,6,8 m
•exact lengths within the manufacturing lengths
•multiples of the exact lengths
Pipes with multiple lengths of the exact lengths included within the lengths of manufacturing, are delivered with an addition of
500 for everycross-cut if it is not provided otherwise in the orders.
The limit deviation for length is:+0-100 mm
The limit deviations for the thickness of the wall <3 mm is of:+ 0,30 mm / - 0,25 mm
The limit deviation for the thickness of the wall >3 mm is of:+ 0,33 mm / - 0,25 mm
Aspects:
The external and internal surface of the pipes must be smooth, without fissures, cracks, superpositions of the material, non-
metallic inclusions. There are admitted small scratches, eminences, hollows, a thin mill cinder or traces of cleaning of the faults
resulting from the manufacturing process, so that the thickness of the wall should not fall under the admitted minimum limit.
The welding joint must be compact and continuous, without fissures or other faults, which would reduce the resistance of the
welding joint under that of the basic metal.
The external prominence of the welding joint is moved off. The thickening of the welding joint is admitted within the limits of
limit deviations for the external diameter. The interior burr of the welding joint is not moved away. Unevenness of the margins of
the strips in the welding joint is not admitted. The ends of the pipes must be smoothed orthogonallyto the axis of the pipe. At
the endings of the pipes is admitted a burr resulting from the technological procedure of cutting. There are not admitted the
strains of the endings of the pipe.
Deliveryterms:
The pipes are delivered without heat treatment, as it results from the process of manufacturing. With the agreement of the
parties, the pipes maybe delivered in normalized state.
Protection:
The pipes are usuallydelivered without protection, but theycan also be delivered with a protecting anticorrosion coating.

Delivery lengths:
Exact or multiple lengths: 6-12 m. Deviation limits: +/- 100 mm
Aspect:
On the surface of the bar there is admitted a thin layer of oxides, on condition, that after cleaning, the resulting
dimension must not be under the minimum dimension admitted. Breaks or ribs are not admitted, and neither are
admitted dislevelments on the surface of the section, resulting from calibration, on condition, that the section should
be included in the admitted area.
Delivery terms:
The steel concrete with the nominal diameter of maximum 12 mm is delivered in coils, and over this diameter in
joints of bars.
29
Dimensions and ribs:
The steel concrete with periodic section must have on the surface antipodal longitudinal ribs, with constant
dimensions on the whole length and spiral ribs situated at equal distances, inclined with 55-56 degrees in relation to
the longitudinal ribs. The spiral ribs are disposed on the same direction, on both halves of the section.

The lateral overlapping of 88 mm,
bigger than in the case of the other
panels, assures an increased
protection against the weeping, even
in the case of hard wind or rain.
Simply convincing!
Way of order:
In order to choose the most favourable product, there must be followed the
following aspects: the place and the domain of use, the environment, the loading
that it will be exposed to.
The protection layer must be specified for both (sur)faces.
Example:
35
folded coloured sheet
These products are made of treated (covered) steel sheet with different fireproof organic materials.
Domains of use: in exterior and interior constructions.
The structure of the products: simple or multiple lacquer layer, of different quality and thickness, with or without protecting foil that can be
moved off. Usually, there are applied organic layers and covering layers on the sheet's two surfaces.

The influence of the components on the behaviour of the material:
Copper:
Titanium:
rises the mechanical resistance and accelerates
the formation process of the patina on the surface of the
material.
rises the fluidity of the metal, improves the factor
of the thermal dilatation with the purpose of reducing the
weight of the metal load.
For the dimensioning of the channels, there must firstly
specified the diameter of the casing, and the dimension of the
channel must be carried over to this amount, according to
MSZ-04-134:1991.
In the next table, it is taken into consideration a storm load of
approximately 300 l/sxha. On the basis of the knowledge of
the standard size, there are calculated according to EN 612
the tubes with circular section and the dimension of the

Important rules for setting into operation (assembling):
The suspended channels with semicircular section will be assembled on the section comprised between the high starting point and that of
arrival situated lower, with the adjustment of a slope of 3-5 mm /m. During the assembly, it must be followed, that the external edge of the
frontal side or the edge of the interior side should be situated with minimum 10 mm lower than the height of the rabbet of the back wall!
(without rabbet this value is in the case of the back wall of minimum 15 mm).
Through a proper technical solution the overtake of the tensions resulting from the movements of longitudinal thermal dilatation can be
solved. This solution may be one with a closing plate in the high points, a dilatation element with an intermediary coating of rubber assembled
on the plane of fluidity respectively a suspended element of pouring, with mobile joint through superposition of the conduct in that point. In
case of technical problems occurred in connection with the assembly, please contact our consultants of specialty.
